DTC123TKAT146 产品概述

基本信息

DTC123TKAT146 是一款高性能的 NPN 预偏置数字晶体管,专为各种电子设备和电路应用而设计。它具有出色的电气特性和高频响应能力,能够在多种工作条件下提供稳定的性能。这款晶体管的典型应用包括开关电路、信号放大,以及其他需要快速切换和高电流增益的场合。

关键参数

  1. 晶体管类型: NPN 预偏置

    • DTC123TKAT146 属于 NPN 型晶体管,适用于正向电流的放大和开关控制,预偏置特性使其在降低驱动电流方面更为高效。
  2. 电流 - 集电极 (Ic): 最大值 100mA

    • 该晶体管能够处理的最大集电极电流为 100 毫安,能够满足中等负载的驱动需求,适合用于相对较小的负载控制中。
  3. 电压 - 集射极击穿 (Vce): 最大值 50V

    • 最大集射极击穿电压为 50 伏,适用于大部分低压应用,这一特性使其在稳压工作条件下表现良好。
  4. 电流 - 集电极截止 (最大值): 500nA

    • 在无激励状态下,集电极截止电流极小(最大500nA),这意味着在待机状态下的功耗极低,有助于提升整体电路的能效。
  5. 频率 - 跃迁: 250MHz

    • DTC123TKAT146 拥有 250MHz 的高频跃迁特性,适用于需要快速切换操作的应用,如无线通信和高频信号处理。
  6. 功率 - 最大值: 200mW

    • 最大功耗为 200 毫瓦,确保在实际应用中不会因过载而损坏。这使得产品适用于一般的信号放大和开关控制。
  7. 封装: TO-236-3,SOT-23-3

    • 采用表面贴装型(SMT3)封装,方便于自动化生产。其小巧的封装设计适合于紧凑型电路布局,非常适合现代小型设备的设计需求。
  8. 电阻器 - 基极 (R1): 2.2 kOhms

    • 标配 2.2k 欧姆的基极电阻器,使得晶体管在需要时能够充分偏置,为快速有效的开关和放大提供了良好的基础。
  9. 不同 Ic、Vce 时的 DC 电流增益 (hFE): 最小 100 @ 1mA,5V

    • DTC123TKAT146 在低电流条件下仍然具备较高的增益,增益值满足各类应用需求,帮助实现信号的有效放大。
  10. Vce 饱和压降: 最大 300mV @ 250µA,5mA

    • 低饱和压降减少了功耗,并提高了电路的整体效率,尤其在与其他逻辑电路连接时表现优异。

应用场景

DTC123TKAT146 非常适合用于多种应用场景,包括但不限于:

  • 开关电路: 由于具备高频和低饱和压降特性,DTC123TKAT146 可以在控制较大电流的开关电路中作为驱动元件,提高响应速度和效率。

  • 信号放大: 在音频、视频和数据传输线路中,DTC123TKAT146 可以用作信号放大器,将微弱信号放大以便后续处理。

  • 微控制器接口: 它适合用作微控制器的驱动接口,以控制继电器、LED 显示器和其他外设的开关状态。

  • 无线通信设备: 由于其高频处理能力,DTC123TKAT146 可有效应用于各种无线通信模块,提供稳定的信号传输和接收能力。

总结

DTC123TKAT146 是一款高效、便捷的 NPN 预偏置数字晶体管,其优异的电气特性和小巧的封装设计,使其成为现代电子设备的重要组成部分。无论是在高频开关,还是在信号放大应用中,DTC123TKAT146 都展现出良好的性能,是电子工程师和设计师在选择晶体管时值得考虑的选择。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
